If the Earth could speak…well, it can

A research team at the University of Iowa has released a new recording of the sound the Earth broadcasts to outer space, a phenomenon otherwise known as “chorus.” The recording, made on Sept. 5, captures radio waves magnetosphere that surrounds the Earth.

The radio waves, which are at frequencies that are audible to the human ear, are emitted by the energetic particles in the Earth’s magnetosphere.

“People have known about chorus for decades,” said the project’s principal investigator, Craig Kletzing in a press release. “Radio receivers are used to pick it up, and it sounds a lot like birds chirping. It was often more easily picked up in the mornings, which along with the chirping sound is why it’s sometimes referred to as ‘dawn chorus.’”

There are other recordings of the sounds of space, including this spooky collection that will help you get ready for Halloween. And, this slideshow offers audio and additional details, but you may not want to listen to Saturn alone in the dark.
